Bite Tabs
Bite wing x-ray

Mesial surface of
canine to distal
surface of 1st
permanent molar
Bite wing x-ray
Incipient carious
lesion.
 Overlapping –
common error

Occlusal Radiographs
Occlusal Radiographs

Posterior max.
occlusal radiograph
Extra Oral film

Lateral Film
Trauma
Soft tissue Film
 Indicated after
trauma to locate
missing piece(s) of
fractured tooth.

Panaramic radiograph
Radiographic diagnosis of
dental anomalies

Ankylosis
Anomalies

Gemination :
unsuccessful
attempt of an
individual tooth bud
to divide into two.
Anomalies

Dilaceration
Anomalies
Peg lateral
 Supernumary
primary lateral

Anomalies
Fusion: dentinal
union of two teeth.
b) Supernumary tooth
c) Missing lateral
a)
Anomalies

Concrescence:
fusion with a
cemental union.
Anomalies
Amelogenesis
Imperfecta
a) Thin enamel
b) Increased dentin

Anomalies

Unfavorable
resorptive pattern of
roots.
Pathology

Retained primary
root tips.
Pathology

Furcation
involvement
Pathology

Furcation
involvement with
internal root
resorption.



Cervical burnout
Mach band phenomenon
It may take 30%-70%
demineralisation to occur before it can
be evidenced radiographically.
Radiographs are 2D views of 3D
objects.
